Review comment:
I see `100f` a couple of times on the code, there is also `100.0f`.
What do you think of extracting these _magic_ `100f`/`100.0f` into a
constant?
Another approach that would be even nicer would be to have these pieces
extracted to a method like `calculateResourceAllocatedPercentage`, and add a
few unit test case methods.
```
public String calculateResourceAllocatedPercentage(float resource, float
resourceWithOverprovisioning) {
return decimalFormat.format(((float)resource /
resourceWithOverprovisioning * 100f)) + **"%"**
}
```
